PIVOT-HINGE FOR WINDOW-SASH'ES.

Specification of Letters Patent.

Patented J an. 16, 1917.

Application filed May 4, 1916. Serial No. 95,368.

To all whom it may concern.-

Be it known that L'Roenn'r ABBIE Ginnins, a subject of the King of Great Britain, and a resident of the municipality of Burnaby, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Pivotllinges for Window- Sashes, of which the following is a specification.

My invention relates to improvements in pivot hinges for window sashes, and the ob ject of my invention is to devise a simple, inexpensive and effective means adapted to be applied to wood or iron sashes of any designs, whether box frames, solid frames, bulls eye, or the like so that the sash may be reversed at will to permit of the outside of the window being cleaned from the room side, thus eliminating entirely the risk of accident which is always present where the cleaner has to sit outside on the window sill to clean the outside of the window, as at the present time.

A further object is to provide a device the use of which when applied to sashes enables the same to be set at any angle between the horizontal and vertical position, thus providing for the ventilation of a room in a simple and convenient manner.

I attain these objects by the construction illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the hinge. Fig. 2 is a perspective view of one half of the hinge. Fig. 3 is a perspective view of the other half of the hinge. Fig. 4 is a sectional plan view taken on AB in Fig. 1. Fig. 5 is a side view, showing the hinge with the parts in the reversed position. Fig. 6 is a fragmentary front view illustrating the application of the hinge to a sash. Fig. 7 is a sectional plan view taken on the line C-D in Fig. 6.

Similar figures of reference indicate similar parts throughout the several views.

My device when assembled is as shown in Fig. 1 and consists of two plate members 1 and 2 respectively provided with lugs 8 and 4 having holes 5 and 6 therethrough, in which holes is disposed the pin 7 to pivotally connect the two members together. The member 1 has an integral portion 8 projecting from its inner face, the edge of which portion is formed semi-circular, as at 9 in Fig. 2, while the member 10 has a portion 11 projecting from its inner face, the

the line edge of which portion is formed as shown at 12 in Fig. 3, and adapted to fit slidably over the semi-circular edge of portion 8 when the device is assembled as at 13 in Fig. 1 and 14 in Fig. 4.

15 indicates a recess formed in the portion 11, in which recess is fitted a plunger 16, the point'of which extends normally beyond the face of the portion 11, as shown in Figs. 3 and 4, and engages one of the countersinks indicated at 17 in Figs. 1, 2, 3 and 4. The plunger is pressed outwardly by means of a spring 18 which fits the recess 15 and is disposed over the stem 19 of the plunger, which stem passes slidably through the portion 11, as shown in Fig. 4 and is held in place by means of a washer 20 over which the end of the stem is riveted.

The countersinks or depressions 17 are arranged on an arc of a circle the center of which is the center of the pin 7, from which it will be seen that, if the member 2 be moved around the pin 7 as shown dotted in Fig. 5, the point of the plunger 16 will enter each countersink successively and therefore, should the member 2 be set in any angled position, as shown in Fig. 5, it will be held there and temporarily locked by the engagement of the point of the plunger 16 in one of the countersinks. It will be apparent that on account of the rounded construction of the point of plunger 16 the member 2 may be moved in any direction when sufficient force is exerted thereon to cause the plunger to be moved inwardly by the sliding action of the plate 2 over the plunger point.

The manner in which the device is applied to a window sash will be clearly seen on reference being made to Figs. 6 and 7, in which 21 represents part of the window frame and 22 the glass. The window stile is formed in two pieces, 23 and 24, as shown in Fig. 6, having a cross section similar to that shown in Fig. 7. The piece 23 of the stile slides on the window frame and to this piece the weight cord is attached. The other piece 24 carries the glass. The hinge, assembled as shown in Fig. 1, is fitted between the two pieces 23 and 24 and intermediate the height of the window, the member 1 being secured to the piece 23 by means of screws 25 through the holes 26 in the plate while the member 2 is secured to the piece 24 in a similar manner by means of screws 27 through the holes 28. It will, of course, be understood that there is one hinge, such as described in the foregoing, fitted at each side of the window.

It will now be seen that the window may be moved around on the hinges in the manner already indicated with reference to the action of the hinge itself so as to reverse the window and bring the outside of the glass to the inside of the room so that it may be cleaned without danger, and further, that the window may be set in any angled position, being temporarily and automatically locked by means of the engagement of the plunger 16 in one of the countersinks 17, as hereinbefore described.

In order to prevent the window from traveling past the proper vertical position when being returned from the reversed position, stops, preferably formed as shown in Figs. 6 and 7 are provided, these stops being indicated by the numerals 29 and 30 respectively. The stop 29 is secured to stile piece 24 and the stop 30 is secured to stile piece 23, from which it will be seen that stop 29 moves with the window. Thus, when the Window arrives at its vertical posi tion, stop 29 engages with the check 31 formed in stile piece 23 while the check 32 formed in stile piece 24; engages the stop 30 secured to stile piece 23. The window is therefore prevented from moving in any direction other than that required to reverse it when necessary.

What I claim as my invention is:

A hinge comprising a plate member provided with a'plurality of depressions arranged circularly on its inner face and having an inwardly extending portion one edge of which is formed are shaped, a plate member having an inwardly extending portion one edge of which is adapted to be mounted 011 the are shaped edge of the first men,- tioned inwardly extending portion, means for pivotally connecting both plate members together, the axis of said pivotal connection being beyond spring plunger carried by the last mentioned plate member adapted to co-act with the depressions in the first mentioned plate member and lock said members together in any desired position.

Dated at Vancouver, B. C., this 25th day of April, 1916.
